I am having quite a weird issue here. I am dynamically loading images into a page. These images are stored in the database. I have a generic file handler that returns the image, and contains the following code:

GetClientUploadFileDetails_Result img = dataContext.GetClientUploadFileDetails(HttpContext.Current.User.Identity.Name, imageID).First();
                HttpContext.Current.Response.Clear();
                HttpContext.Current.Response.AddHeader("content-disposition", string.Format("inline; filename=\"{0}\"", img.Logo_name));
                HttpContext.Current.Response.ContentType = img.Mimetype;

                if (HttpContext.Current.Response.IsClientConnected)
                    HttpContext.Current.Response.BinaryWrite(img.ImageData);

The images load in Chrome and FF, but do not in IE?? If I inspect the element in IE and click on the src link, it goes to a new page and shows the image? I cannot see why this isnt working?
